Old Exam Problems - Options - Solutions Page 2 of 13 Pages C d = [(.3)($2.336) + (.7)($0.000)]/[1.01] = $0.694 C 0 = [(.3)($3.596) + (.7)($0.694)]/[1.01] = $1.55 2. Assume that a share of stock has a current price of $65. Also assume that a call option on this stock has 1 year to maturity and that the appropriate 1-year interest rate is 5.00%. Using the N(d) table, you can calculate that when the standard deviation of the continuously compounded annual returns is 0.23, that N(d1) will be 0.6282, N(d2) will be 0.5387, and the price of the call option will be $7.49. Now assume that there is major change in the market, such that the annual interest rate goes up to 8.00% while the standard deviation of return goes down to 0.18, which in turn will force N(d1) up to 0.6976 and N(d2) up to 0.6322. What will be the change in the price of the call option?
